The process is known as Translocation. Translocation is the transport of manufactured food substances like sucrose and amino acids( Substances in the cell sap) from their place of origin to other plant parts through the phloem tissue.
The phloem distributes food and nutrients and sugars from photosynthesis to the rest of the plant. basically it is apart of the photosynthesis act. if you need any thing else go to class for a while and mayb you wont need to look on the internet.

Plant tissues that conduct foods made in the leaves to all other parts of the plant.

Phloem transports prepared food material to different parts of the plant from leaves and other strorage organs for food.
it is always source to sink.
translocation
The movement of sugars in the phloem begins at the source, where (a) sugars are loaded (actively transported) into a sieve tube. Loading of the phloem sets up a water potential gradient that facilitates the movement of water into the dense phloem sap from the neighboring xylem (b). As hydrostatic pressure in the phloem sieve tube increases, pressure flow begins (c), and the sap moves through the phloem by mass flow. Meanwhile, at the sink (d), incoming sugars are actively transported out of the phloem and removed as complex carbohydrates. The loss of solute produces a high water potential in the phloem, and water passes out (e), returning eventually to the xylem.
Yes, this facilitates the distribution of food material to all parts of the plant equally well.
phloem
Phloem has a two-way flow
Water goes up from the roots and the food goes to all parts of the plant.

The pressure flow theory describes the movement of food through the phloem. The theory was originated by Ernst Munch.
The Leaf
Yes, this facilitates the distribution of food material to all parts of the plant equally well.
Xylem is different from phloem structurally and functionally.Xylem consists of Tracheids, vessels and xylem parenchyma whereas phloem consists of Sieve tubes, companion cells and phloem parenchyma.Xylem conducts water and minerals to the leaves whereas phloem transports the prepared food from leaves to different parts of plant body.
The sieve tubes of the phloem cells help to transport sugars. The stem of the plant has a layer of cells called phloem. Part of the phloem is made of sieve tubes that permit the flow of sugars solution through the influence of fluid pressure differential. The phloem also contains companion cells for the sieve tubes which aid in the transport of sugars to these tubes.

the food made in the leaves travel through stem to the roots.
